I have my tower fan 6-10 feet inside the colder room, pointing at the doorway to the stove room. That's mostly because it's a good spot to keep it out of everyone's way. There's no way I could tolerate having to step around any fan, and certainly not an ugly loud box fan.Same placement - 6 to 12 inches from the doorway?
It's not to cold. I'm just cheap and hate to pay eversorce for electricity
